The differential dz = 2x2y3dx + 3x3y2dy is an inexact differential.

To determine if a differential is exact or inexact, we need to compare the partial derivatives of the two terms. If the partial derivative of the first term with respect to y is equal to the partial derivative of the second term with respect to x, then the differential is exact.

For the first term, the partial derivative with respect to y is:

∂(2x2y3)/∂y = 6x2y2

For the second term, the partial derivative with respect to x is:

∂(3x3y2)/∂x = 9x2y2

Since these two partial derivatives are not equal, the differential is inexact.

Therefore, the differential dz = 2x2y3dx + 3x3y2dy is an inexact differential.

the measure of the largest angle of the triangle is Largest angle = 4x + 10 = 4(25) + 10 = 110 So, the largest angle of the triangle has a measure of 110 degrees.

tLet x be the measure of the smallest angle of the triangle.

According to the problem statement, the measure of the largest angle of the triangle is 10 more than 4 times the measure of the smallest angle. Therefore, we can write:

Largest angle = 4x + 10

The measure of another angle is 20° more than the smallest angle. Therefore, we can write:

Other angle = x + 20

Since the sum of the measures of the angles in a triangle is always 180 degrees, we can write an equation based on this fact:

Smallest angle + Largest angle + Other angle = 180

Substituting the expressions we have for the largest angle and the other angle, we get:

x + (4x + 10) + (x + 20) = 180

Simplifying the expression, we get:

6x + 30 = 180

Subtracting 30 from both sides, we get:

6x = 150

Dividing both sides by 6, we get:

x = 25

Therefore, the measure of the largest angle of the triangle is:

Largest angle = 4x + 10 = 4(25) + 10 = 110

So, the largest angle of the triangle has a measure of 110 degrees.

The descriptions of the average distance from the earth to the moon cannot both be correct. At least one of them must be wrong.

The average distance from the earth to the moon is a well-established scientific measurement, and it is highly unlikely for two reputable sources to provide significantly different values for such a widely known and studied parameter.

The accepted average distance from the earth to the moon is approximately 384,400 kilometers.

This value has been determined through extensive astronomical observations and measurements.

While small variations in measurements may occur due to factors like the moon's elliptical orbit, these variations are typically within a narrow range.

Therefore, a difference of 467 kilometers between the two given values is significant and suggests that at least one of the descriptions is incorrect or based on inaccurate information.

Step-by-step explanation:

Therefore, probability solution is estimating this likelihood without additional data or analysis is inappropriate correct response is option a.

The main goal of the mathematical branch known as statistical inference is to estimate the likelihood that a statement is accurate or that a particular event will take place. Any number among 0 and 1, where 1 typically denotes confidence and 0 typically denotes possibility, can be used to symbolise chance. A probability diagram illustrates the likelihood that a particular occurrence will take place.

Here,

Because of the skewed demographic distribution, the right response is (a).

We could use the normally distributed to compute probabilities because the length of adult American ladybirds is distributed normally with a known standard deviation. The normal distribution may not, however, correctly depict the distribution of ladybird lengths in the population due to the skewed population distribution.

Furthermore, even if the difference between the actual community mean and the assumed mean of 1 cm is tiny, the given size of the population of 440000 could result in a statistically significant outcome.

However, because the assumption of normality may not hold true, this does not imply that we can accurately determine the likelihood of a random ladybird in Raleigh being larger than 1.5 centimetres.

Therefore, estimating this likelihood without additional data or analysis is inappropriate.

The estimate of the standard deviation (Sp) for the total number of errors in assignments from various semesters is approximately 0.044996 and the upper control limit (UC) is approximately 0.374988, and the lower control limit (LCL) is approximately 0.105012 for the p chart.

To compute the estimate of the standard deviation (Sp), we need to determine the proportion of assignments with errors in each semester and calculate the overall proportion of assignments with errors.

Given:

Number of semesters (n) = 5

Total number of assignments per semester (nupper) = 150

Proportion of assignments with errors (p) = 0.24

First, we calculate the proportion of assignments with errors for each semester:

Semester 1: p1 = (150 * 0.24) / 150

= 0.24

Semester 2: p2 = (150 * 0.24) / 150

= 0.24

Semester 3: p3 = (150 * 0.24) / 150

= 0.24

Semester 4: p4 = (150 * 0.24) / 150

= 0.24

Semester 5: p5 = (150 * 0.24) / 150

= 0.24

Next, we calculate the overall proportion of assignments with errors:

p = (p1 + p2 + p3 + p4 + p5) / n

= (0.24 + 0.24 + 0.24 + 0.24 + 0.24) / 5

= 1.2 / 5

= 0.24

Now we can compute the estimate of the standard deviation (Sp):

S = √((n - 1) * (1 - p) / n)

= √((5 - 1) * (1 - 0.24) / 150)

= √(4 * 0.76 / 150)

= √(0.304 / 150)

≈ √0.0020267

≈ 0.044996

Finally, we can compute the upper control limit (UC) and lower control limit (LCL) for the p chart using the formula:

UC = p + (3 * Sp)

LCL = p - (3 * Sp)

UC = 0.24 + (3 * 0.044996)

= 0.24 + 0.134988

≈ 0.374988

LCL = 0.24 - (3 * 0.044996)

= 0.24 - 0.134988

≈ 0.105012

Answer:

  -6 < x < 2

  see attached for a graph

Step-by-step explanation:

You want the solution to 3 > -x -3 > -5 expressed as an inequality and as a graph.

Multiplying by -1, we need to reverse the inequality symbols:

  -3 < x + 3 < 5

Now, we can subtract 3 to get the solution as an inequality.

  -6 < x < 2

The graph is in the attachment.

__

Additional comment

There are open circles at the boundary points because the "less than" (<) inequality means the boundary points are not included in the solution set.

First we need to find the inverse function.  To do this, I'd put f(x) into vertex form:

    \(\begin{aligned}f(x) &= (x^2-4x)-6\\[0.5em] &= (x^2-4x+4)-6-4\\[0.5em] &= (x-2)^2-10\\[0.5em]\end{aligned}\)

Now, we can try to invert the function, keeping in mind this is only used when x≥2.

     \(\begin{aligned}y&= (x-2)^2-10\\[0.5em]y+10&= (x-2)^2\\[0.5em]\sqrt{y+10}&= x-2\\[0.5em]\sqrt{y+10}+2&= x\\[0.5em]\end{aligned}\)

(The fact that x ≥ 2 allowed us only keep the positive square root on the third line.)

So our inverse function is \(f^{-1}(y)=\sqrt{y+10}+2\).

Now, let's find the derivative of this function:

    \(\begin{aligned}\dfrac{df^{-1}}{dy}&= \dfrac{1}{2\sqrt{y+10}}\cdot\dfrac{d}{dy}[y+10]\\[0.5em] &= \dfrac{1}{2\sqrt{y+10}}\end{aligned}\\\)

(The chain rule was used, but the derivative of the inside function equals 1.)

So \((f^{-1})'(-6) = \dfrac{1}{2\sqrt{-6+10}} = \dfrac{1}{4}\)

Now having done all of that, it did cross my mind that since \(f\) and \(f^{-1}\) are simply reflections over the line y=x, if we had actually just found f'(4) and then used the reciprocal slope, we'd also get the same answer more quickly.

f'(x) = 2x - 4

when y = -6, then x = 4 (by solving f(x) = -6).

f'(4) = 4, so reflecting that slope of 4/1 over the line y=x, we'd get a slope of 1/4.

Using the divergence theorem we can compute that the outward flux of the vector field is 16π .

The outward flux of F over the solid cylinder and z = 0 is

∫∫F·ds  = ∫∫∫ DivF dv

F = 2xy² i   +  2x²y j + 2xy k

Div F  =  D/dx (2xy²)  +   D/dy (2x²y )

Div F  =  2y²  +  2x²

In cylindrical coordinates   dV = rdrdθdz and as z = 0 the region is a surface ds = r·dr·dθ

Using the parametric form of the surface equation

x = rcosθ        y =  r sinθ      and z = z

Div F  = 2r² sin²θ  + 2r²cos²θ

∫∫∫ DivF dv  =  ∫∫ [2r²sin²θ  + 2r²cos²θ] × rdrdθ

∫∫ 2r² [sin²θ  + cos²θ] × rdrdθdz   ⇒  ∫∫ 2r³ drdθ

Integration limits

0 < r < 2          0 < θ < 2π

2∫₀² r³ ∫dθ

The divergence theorem, commonly known as Gauss' theorem or Ostrogradsky's theorem, is a theorem that connects the flow of a vector field across a closed surface to the field's divergence in the volume enclosed.

In more detail, the divergence theorem states that the surface integral of a vector field across a closed surface, sometimes referred to as the "flux" through the surface, is equal to the volume integral of the divergence over the region inside the surface.

Therefore the flux is 16π .

The probability that the distance between them is more than the radius of the circle is given as follows:

0.5 = 50%.

A probability is calculated as the division of the desired number of outcomes by the total number of outcomes.

For the circle, we have that the radius is the distance between any point on the circumference of the circle, and the center.

The largest distance is the diameter, which is the distance between two points on the circumference of the circle, passing through the center.

The diameter is twice the radius, hence the probability is given as follows:

The monomial of the expression given the cube of that monomial -0.001a^(3n+3) is; x = (-1/10)a^(n + 1)

A monomial is defined as a polynomial, that has only one term. A monomial is also defined as an algebraic expression possessing a single term but can as well possess multiple variables as well as a higher degree also.

We are given the expression;

x³ = -0.001a^(3n + 3)

Now, -0.001 can also be expressed as -1/10³. Thus, we have;

x³ = (-1/10³)a^(3n + 3)

Factorizing the exponent gives;

x³ = (-1/10³)a^[3(n + 1)]

Since the terms are both cubed, then we can write as;

x³ = [(-1/10)a^(n + 1)]^3

The correct values for a, b, c, d, and e are a = 16, b = 29, c = 24, d = 22, and e = 30 for group of 75 students on asking whether they like Algebra or Geometry.

For the values of a, b, c, d, and e, we can use the information provided in the table. Let's break it down step-by-step:

We are given that a total of 75 math students were surveyed. Therefore, the total number of students should be equal to the sum of the students who like algebra, the students who like geometry, and the students who do not like either subject.

75 = 45 (Likes Algebra) + 53 (Likes Geometry) + 6 (Does Not Like Either)

Simplifying this equation, we have:

75 = 98 + 6

75 = 104

This equation is incorrect, so we can eliminate options c and d.

Now, let's look at the information given for the students who do not like geometry. We know that a + b = 6, where a represents the number of students who like algebra and do not like geometry, and b represents the number of students who do not like algebra and do not like geometry.

Using the correct values for a and b, we have:

16 + b = 6

b = 6 - 16

b = -10

Since we can't have a negative value for the number of students, option a is also incorrect.

The remaining option is option e, where a = 29, b = 16, c = 24, d = 22, and e = 30. Let's verify if these values satisfy all the given conditions.

Likes Algebra: a + c = 29 + 24 = 53 (Matches the given value)

Does Not Like Algebra: b + d = 16 + 22 = 38 (Matches the given value)

Likes Geometry: c + d = 24 + 22 = 46 (Matches the given value)

Does Not Like Geometry: b + e = 16 + 30 = 46 (Matches the given value)

All the values satisfy the given conditions, confirming that option e (a = 29, b = 16, c = 24, d = 22, and e = 30) is the correct answer.

Accoding to the calculations , the correct answer is:

A) Depreciation charge 16,000; revaluation surplus £20,000

According to IAS 16 Property, Plant and Equipment, the depreciation charge for an asset should be based on its carrying amount, useful life, and residual value.

In this case, the buildings were purchased for £400,000 (£480,000 - £80,000) and had a useful life of 25 years. Since there is no residual value, the depreciable amount is equal to the initial cost of the buildings (£400,000).

To calculate the annual depreciation charge, we divide the depreciable amount by the useful life:

£400,000 / 25 = £16,000

Therefore, the depreciation charge for the year ended 30 September 2021 is £16,000.

Now, let's calculate the balance on the revaluation surplus as at that date.

The revaluation surplus is the difference between the fair value of the property and its carrying amount. On 1 October 2020, the property was revalued to £500,000, and the carrying amount was £480,000 (£400,000 for buildings + £80,000 for land).

Revaluation surplus = Fair value - Carrying amount

Revaluation surplus = £500,000 - £480,000

Revaluation surplus = £20,000

Therefore, the balance on the revaluation surplus as at 30 September 2021 is £20,000.

Based on the calculations above, the correct answer is:
